A conductor has a circular cross-sectional area A, length L, and L resistivity p, as shown. A Suppose you want to double the resistance of the conductor. Would the following changes achieve this goal? i) Yes No Replace the conductor with one made from a material with half the resistivity, keeping everything else the same: ii) Replace the conductor with one made from a material with half the conductivity, keeping everything else the same: Yes No Double the length of the conductor, keeping everything else the same: iii) Yes No Double the radius of the conductor, keeping everything else the same: iv) Yes No Yes Reduce the radius of the conductor by half, keeping everything else the same: v) No
